Originally i use to have a Windows XP partition on my mac desktop. I even created a shortcut to a folder in windows "Music". Then, i installed Parallels 4.0. Superb. I love how it works. Then, i opened the "Music" folder through Parallels. Nothing wrong. Same time, I opened the "Music" folder again through my mac desktop (I forgot I opened it in the first place). I copied a song INTO the folder. Still fine. Closed the "Music" folder accessed from my desktop shortcut. But, then when i went back to my "Music" folder from Parallels, the song wasn't there. Opened "Music" folder through my desktop shortcut and the file was there BUT in the form of "X FILE". It was suppose to be .mp3 turned into .x (file type: x file). I cannot delete it and here's where it turned bad. My whole windows XP partition became locked. "FOLDER could not be modified" is the error everytime i tried to add, delete or do anything in the partition through my mac. Even when i shut down, restarted, rebooted parallels, rebooted into boot camp, no difference. I can modify it through Parallels but not directly anymore like last time. What happened? So sorry for the long story.
